Generate random IPv4 or IPv6 addresses, optionally skip reserved ranges, and inspect whether the result looks public, local, multicast, or loopback.
Generated with secure browser randomness when available.
IPv4 output is built from four random octets, while IPv6 output is built from eight random 16-bit groups rendered in hexadecimal form.
When filtering is enabled, the generator retries if a result lands in common local or special-purpose ranges such as private, loopback, multicast, link-local, and documentation space.
No. It generates address-shaped values and optionally avoids common local and special-purpose ranges, but it does not verify real-world routing or allocation.
Some workflows want public-style examples, while others need private, local, or special-purpose addresses for testing.
No. The tool shows all eight groups explicitly so the structure is easy to inspect.
They are useful for fixtures, UI tests, tutorials, log samples, and network-related mock data.
Address formatting alone does not make an IP usable on the public internet.
Filtered mode is best for generic examples, while unfiltered mode is better for network edge cases.
Filtered mode avoids several common special-purpose ranges, but it is not a full IANA registry validator.
IPv4 uses dotted-decimal notation and IPv6 uses colon-separated hexadecimal groups.
